– Many researchers, in several contexts, have investigated the influence of audit committee effectiveness and audit quality variables on reducing the extent of earnings management, and empirical evidence is rather inconsistent.
– The aim of this paper is to meta-analyze the results of 58 prior studies that examined whether differences in results are related to moderating effects associated with corporate governance mechanisms or measures of earnings management.
– The findings show that the meta-analysis identifies many significant relationships. The independence of the audit committee, its size, expertise and the number of meetings have a negative relationship with earnings management. Similar negative relationships exist between auditor size, specialization and earnings management.
– This study contributes to the corporate governance literature. Further, recognizing the function of an audit committee and audit quality shows the value of considering an institutional setting in governance research. This study is significant to academic and practitioner literatures, policy makers and professional accounting bodies as it shows that governance reforms promote companies to adopt good governance practices. The results also give useful information to investors in examining the effect of audit committee characteristics and audit quality on earnings quality.
– This study extends existing research on audit committee and audit quality to oversee both accrual and real earnings management using meta-analysis. Thus, this study has the potential to help stakeholders, board of directors, regulators and auditors, who are related with enhancing the supervision of firms and reducing the opportunities given to managers, to engage in earnings management.
